“…Second, it is quite difficult not to disturb field samples when taking them to the lab. Third, evaporation during the rainfall events is not taken into account, which is also the case for the method of Pathak et al (1985), who measured that 8-12% of the net precipitation was evaporated. Despite these arguments, Helvey and Patric (1965) stress that the difference is caused by the "interface effect".…”

“…In this way Putuhena and Cordery (1996) found average storage capacities of 2.8 mm for pine and 1.7 mm for eucalyptus forest floors. Examples of the second category are for example carried out by Pathak et al (1985), who measured the weight of a sample tray before and after a rainfall event. They found litter interception values of 8%-12% of the net precipitation.…”

Abstract. In hydrological models, evaporation from interception is often disregarded, combined with transpiration, or taken as a fixed percentage of rainfall. In general interception is not considered to be a significant process in rainfallrunoff modelling. However, it appears that on average interception can amount to 20-50% of the precipitation. Therefore, knowledge about the process of interception is important. Traditional research on interception mainly focuses on canopy interception and almost completely denies forest floor interception, although this is an important mechanism that precedes infiltration or runoff. Forest floor interception consists partly of interception by dry soil, partly of interception by short vegetation (mosses, grasses and creeping vegetation) and partly of interception by litter. This research project concentrates on litter interception: to measure its quantities at point scale and subsequently to upscale it to that of a hydrotope. A special measuring device has been developed, which consists of a permeable upper basin filled with forest floor, and a watertight lower basin. Both are weighed continuously. The device has been tested in the Huewelerbach catchment (Luxembourg). The preliminary measuring results show that the device is working properly. For November 2004, evaporation from interception was calculated to be 14 mm of 42 mm throughfall (i.e., 34%).

“…Other authors also published data about litter interception of gross precipitation or annual value (Table 4). Litter interception data of the net precipitation (throughfall) was 8-12% in mixed oak stands (Pathak et al 1985), and 34% for November 2004 in beech forests (Gerrits et al 2006). The comparison of our data is uncertain because of different climatic conditions and tree species (mainly due to the weight of litter) and different methods of measurement.…”

-Models that describe hydrological processes in forests may help to estimate the consequences of forestry interventions or of climate change. The authors employed a hydrologic model for estimation of forest litter interception of a middle-aged sessile oak (Quercus petraea) stand. Antecedent water content and the storage capacity of the forest litter were the main parameters of the model. The antecedent water content of the litter was estimated by the daily precipitation and temperature data, collected in Hidegvíz Valley research catchment in a three year measurement period (2006)(2007)(2008). The measurements were done by an instrument we developed ourselves, where the undisturbed forest litter samples were enclosed in frames and measured in daily time steps.interception model / forest litter / forest hydrology Kivonat -Avarintercepció modellezése egy kocsánytalan tölgyesben. Az erdőben lezajló hidrológiai folyamatokat leíró modellek segítenek megbecsülni az erdészeti beavatkozások, és a klímaváltozás következményeit. Jelen munka egy hidrológiai modellel foglalkozik, ami egy középkorú kocsánytalan tölgy (Quercus petraea) állomány avarintercepcióját becsüli. Az avar megelőző víztartalma és tározási kapacitása a modell fő paraméterei. Az avar megelőző víztartalmát a napi csapadék és hőmérséklet adatokból becsültük, melyek a Hidegvíz-völgyi kísérleti vízgyűjtőből származnak a három éves mérési periódus időtartamára (2006)(2007)(2008). Az adatgyűjtést saját fejlesztésű eszközzel végeztük úgy, hogy a bolygatatlan avarminták tömegét zárt keretekben napi gyakorisággal mértük.intercepciós modell / avar / erdészeti hidrológia
